Author Marti Perarnau, a confidant of Guardiola, has now revealed in his new book 'The Pep Revolution', that Sterling and Guardiola had a bust-up in March of 2021 in the Spaniard's office before the winger walked out of the conversation which caused the City boss to drop him altogether from the squad for a clash against Fulham. The furious encounter had started initially after Sterling was benched for Manchester City's 5-2 win over Southampton. The Englishman had been offended by Guardiola's decision and had begun acting up.
